This is often a permission or security software (antivirus, etc) problem.Be sure the user MySQL is running with has the permission to create files in C:\xampp\tmp\.If you are running any security software try to temporary disable it or better configure them to exclude the folder C:\xampp\tmp\

Is the MySQL process started as administrator too?In cases of operating systems with activated user account control Windows denies write access to several sensitive folders (like system32, etc.) even for administrators.But the XAMPP tmp folder should not be restricted.
